The Lowdown
Alright, let’s talk in feet and miles, Rusty style.
We’re in for a painfully quiet stretch at Karramarro. From now until nearly the 27th of August, the surf is basically a no-show. That’s close to two weeks of flat, weak energy and scores that just say “poor.” You can have all the glassy mornings you want, but without any swell, you’re just staring at a lake.
The first real signal comes Thursday morning the 27th. A 5-foot NW swell with a 9-second period rolls in, and the wind is dead glass. The energy picks up to 328 (moderate), and for the first time in ages, the report says “expect good surf conditions.” It’s a lifeline.
But the highlight of the whole 16-day run is Friday the 28th. That morning is the one. A clean 6-foot swell from the NW, period stretching out to 10 seconds, and a nice cross-offshore breeze out of the west. Combined energy hits 783 (moderate-strong). That’s proper groundswell, and it’ll make the point start to draw lines. Just note that Friday afternoon the wind gets heavy and the swell jumps to 8 feet, which flags as questionable for quality, so the morning is your window.
Saturday the 29th goes big—really big. We’re talking 11-12 feet of NW swell with a very long 14-second period. The energy reading is massive at 4178 (very strong). That is serious, heavy water. For a point break, this is strictly for experts. It’s beautiful and powerful, but it’s not a day to learn. The report even calls it marginal, which for that size and period makes sense.
Water is running at 76°, which is much warmer than average for August. That’s a solid 5° above normal, so you’ll be comfortable in a spring suit.
So here’s the plan: sit tight through the dead zone, then Thursday the 27th morning gets you back in the water. Friday the 28th morning is your best bet for clean, solid waves. After that, it’s big-boy territory.
Rusty.

Information about the Karramarro Surf forecast
The above surf forecast table for Karramarro provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Karramarro can be found by selecting the local surf guide option on the grey menu. Our Karramarro surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Karramarro) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Karramarro may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
